After only a little over a week, Apple has now seeded the fifth beta of iOS 10 to developers. Right now we’re only seeing a few new things.
It looks like Apple is reprocessing the facial recognition data in Photos, which means all the facial data will be lost. There’s also a new lock sound. Finally, the Apple battery case now seems to be working properly.
Developers can obtain the latest beta from Settings. Or if you have not downloaded it yet you can do so from the developer center.
